Skill: Remember

Save a decision, convention, or pattern to the project's context scaffold.

When to Use

Run /remember <description> when you want to persist something learned during a session:

• An architectural decision and its rationale
• A naming or structural convention discovered in the codebase
• A reusable pattern worth codifying for future work
• A freeform note that belongs in project context

Process

Step 1: Classify the Input

Read the user's description and classify it into one of three types:

If the classification is ambiguous, ask the user which type fits best. If it truly doesn't fit any category, default to Convention under "Project-Specific Rules".

Step 2: Check for Duplicates

Read the target file and scan for similar existing entries:

• For decisions: check if the same topic is already covered (even with different wording)
• For conventions: check if the same rule exists under any category heading
• For patterns: check if a pattern file covering the same scenario already exists in patterns/

If a similar entry exists:

• Tell the user what you found
• Ask whether to update the existing entry or add alongside it
• If updating, preserve the original date and add an "Updated: YYYY-MM-DD" note

Step 3: Format the Entry

Each target file carries its own authoritative format — follow it rather than reformatting from memory:

• Decision → the ## Format block at the top of decisions.md. Append the new record under ## Entries.
• Convention → the one-line - [Convention]: [Example] — [Why, if not obvious] shape shown under each category in conventions.md. Choose the right category heading (Naming, File Organization, Error Handling, Testing, or Project-Specific Rules); if none fit, use Project-Specific Rules.
• Pattern → the ## Pattern File Format block in patterns/README.md. Create a new .claude/context/patterns/<kebab-name>.md from it; at minimum fill "When to Use" and "Structure", asking the user for anything you can't infer.

If a target file is missing its format header (an older scaffold), fall back to the matching template under templates/context/ — those templates are the source of truth for the schema.

Step 4: Write the Entry

1. Read the target file
2. Insert the new entry in the correct location:
   • Decisions: above the <!-- Add new decisions above this line --> comment
   • Conventions: under the appropriate ## category heading, above the <!-- Add new conventions above this line --> comment
   • Patterns: create new file in .claude/context/patterns/
3. Do NOT modify ## Manual Notes or anything below it

Step 5: Update ROUTER.md (Patterns Only)

If a new pattern file was created:

1. Read .claude/context/ROUTER.md
2. Add the pattern to the Context Files table with its purpose
3. If the pattern is relevant to specific task types, update the Task Routing table
4. Keep ROUTER.md under 50 lines

Step 6: Confirm

Tell the user:

• What type was classified (decision/convention/pattern)
• Which file was written to (full path)
• The exact content that was added
• If a pattern was created, note that ROUTER.md was updated

Scaffold Missing?

If .claude/context/ doesn't exist, tell the user:

Project context scaffold not found. Run /intel first to generate the scaffold structure, then use /remember to add entries.

Do not create the scaffold from scratch — /intel handles that.

Common Mistakes

• Writing to the wrong file — decisions have rationale and tradeoffs, conventions are rules to follow, patterns are structural templates
• Skipping deduplication — always check before adding
• Modifying Manual Notes — never touch content below ## Manual Notes
• Creating trivial patterns — a pattern file should describe something non-obvious and reusable, not a single-line convention
